<P CLASS=para>
An event of this type indicates that an important action has
occurred for a <tt CLASS=literal>Window</tt> object.

<P CLASS=para>
Call <tt CLASS=literal>getWindow()</tt> to determine the <tt CLASS=literal>Window</tt>
object that is the source of this event.  Call
<tt CLASS=literal>getID()</tt> to determine the specific type of event that
has occurred.  Each of the following seven constants
corresponds to one of the methods of the
<tt CLASS=literal>WindowListener</tt> interface:

<P CLASS=para>
<tt CLASS=literal>WINDOW_OPENED</tt>

<P CLASS=para>
This type indicates that the window has been created and
opened; it is only delivered the first time that a window is
opened.

<P CLASS=para>
<tt CLASS=literal>WINDOW_CLOSING</tt>

<P CLASS=para>
This type indicates that the user has requested that the
window be closed through the system menu, or through a close
button on the window's border, or by invoking a
platform-defined keystroke, such as <b>Alt-F4</b> in
Windows.  The application should respond to this event by
calling <tt CLASS=literal>hide()</tt> or <tt CLASS=literal>destroy()</tt> on the
<tt CLASS=literal>Window</tt> object.

<P CLASS=para>
<tt CLASS=literal>WINDOW_CLOSED</tt>

<P CLASS=para>
This event type is delivered after a window is closed by a
call to <tt CLASS=literal>hide()</tt> or <tt CLASS=literal>destroy()</tt>.

<P CLASS=para>
<tt CLASS=literal>WINDOW_ICONIFIED</tt>

<P CLASS=para>
This event type is delivered when the user iconifies the window.

<P CLASS=para>
<tt CLASS=literal>WINDOW_DEICONIFIED</tt>

<P CLASS=para>
This event type is delivered when the user de-iconifies the window.

<P CLASS=para>
<tt CLASS=literal>WINDOW_ACTIVATED</tt>

<P CLASS=para>
This event type is delivered when the window is
activated--that is, when it is given the keyboard focus and
becomes the "active" window.

<P CLASS=para>
<tt CLASS=literal>WINDOW_DEACTIVATED</tt>

<P CLASS=para>
This event type is delivered when the window ceases to be
the active window, typically when the user activates some
other window.
